XPCI(4) BSD/xen Kernel Interfaces Manual XPCI(4) NAME
xpci -- Xen frontend paravirtualized PCI pass-through driver SYNOPSIS
xpci* at xenbus? pci* at xpci? DESCRIPTION
The xpci driver is the frontend part of the PCI pass-through functionality that can be used by Xen guest domains to communicate with PCI devices. From a guest point of view, xpci is similar to a pci(4) bus, except that the guest talks with the PCI backend driver instead of the real physical device directly. When the host domain is NetBSD, the xpci driver is backed by a pciback(4) driver within the dom0. SEE ALSO
pci(4), pciback(4), xenbus(4) HISTORY
The xpci driver first appeared in NetBSD 5.1. AUTHORS
The xpci driver was written by Manuel Bouyer <bouyer@NetBSD.org>. SECURITY CONSIDERATIONS
As PCI passthrough offers the possibility for guest domains to send arbitrary PCI commands to a physical device, this has direct impact on the overall stability and security of the system. For example, in case of erroneous or malicious commands, the device could overwrite physi- cal memory portions, via DMA. BSD
